# Mark a chat read `POST /api/contacts/{phone}/read` (operationId: `markRead`, group: Contacts) Marks every unread customer message in the chat as read. A dashboard session also records that the signed-in team member opened the chat (seen-by). A key marking a chat read is an integration, so nothing is recorded as a person looking. Part of the full API, which is included in the Scale plan. Any one of these scopes is enough: `contacts`. **Parameters** | Name | In | Type | Required | Description | | --- | --- | --- | --- | --- | | `phone` | path | string | yes | Contact phone number with the country code, digits only. A leading + is accepted. A 10-digit number with no country code is treated as Indian (91 is added). | **Response 200**: Marked. Example: ```json { "success": true } ``` Part of the InboxWA API reference: https://inboxwa.online/docs/api . Full reference as one document: https://inboxwa.online/docs/api.md .
